The film discusses the classification of matter into homogeneous and heterogeneous types, focusing on elements, compounds, and mixtures. It explains the properties of two elements, iron and sulfur, ...

Students will learn how to categorize matter as either pure substances or mixtures. Students will apply tests, based on physical properties of matter samples, to determine whether a mixture is ...

Physicists have developed a novel technique that can detect molecular variants in chemical mixtures -- greatly simplifying a process that is one of the most important, though time-consuming, processes ...

An electronic nose modeled on insect antennae simultaneously identifies gas mixtures and pinpoints their three-dimensional ...

A solid sorbent that selectively binds hydrocarbons may help the petrochemical industry reduce costs and energy consumption by increasing the efficiency of—or eliminating—energy-intensive separation ...

When hearing someone describe the typical preparation of organosulfur compounds, it’s clear the approach is not a very sustainable one. Mixtures of sulfur compounds naturally in crude oil are first ...

As oranges are peeled, they spray a tangy, citrus scented oil into the air. The main compound in the fragrant mist is limonene, which can be collected from discarded peels and used in flavorings, ...

IIIF provides researchers rich metadata and media viewing options for comparison of works across cultural heritage collections. Visit the IIIF page to learn more. Green cardboard box containing a ...

Everything we can see and touch, and quite a lot that we can’t as well, is made of tiny particles called atoms. Some substances, like particles of this iron, contain only one kind of atom. Iron is an ...
